Description

Student's dedicated timing pen

Technical field

The utility model relates to a kind of student's dedicated timing pen.

Background technology

At present, conventional student pen only only has writing function, when student needs to have simulated tests, needs optional equipment timer to carry out timing; But, in the situations such as self-study at night, once after setting timer, the tinkle of bells during time reminding will affect other classmates; And if be arranged to silent mode, solve a problem because student is now absorbed in, often ignore the time, thus have impact on timing effect.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of clocking effect good and student's dedicated timing pen that can not impact periphery crowd.

The purpose of this utility model is achieved in that

A kind of student's dedicated timing pen, described student's dedicated timing pen includes a body, described pen is provided with button with it, the finger grip position of described body is set with the piezoelectric vibration piece arranged in tubular structure, described body inside is provided with time-delay relay, battery and resistance, and button, piezoelectric vibration piece, battery and resistant series form primary Ioops, and described piezoelectric vibration piece is parallel with time-delay relay.

A kind of student's dedicated timing pen of the utility model, described pen is provided with a USB interface with it, and be provided with charge management module in described body, described battery is connected to USB interface through charge management module.

Compared with prior art, the beneficial effects of the utility model are:

The utility model structure is simple, easy to use, and can not have any impact to surrounding population in whole timing course, avoids bothering other people; And clocking capability is incorporated on pen by the utility model, thus without the need to optional equipment timer, student is facilitated to carry out simulation test etc. at any time.

Fig. 2 is the circuit block diagram of a kind of student's dedicated timing pen of the utility model.

Wherein:

Body 1;

Button 101, piezoelectric vibration piece 102, time-delay relay 103, battery 104, resistance 105.

Detailed description of the invention

See Fig. 1 and Fig. 2, a kind of student's dedicated timing pen that the utility model relates to, described student's dedicated timing pen includes a body 1, described body 1 is provided with button 101, the finger grip position of described body 1 is set with the piezoelectric vibration piece 102 arranged in tubular structure, described body 1 inside is provided with time-delay relay 103, battery 104 and resistance 105, and button 101, piezoelectric vibration piece 102, battery 104 and resistance 105 primary Ioops in series, described piezoelectric vibration piece 102 is parallel with time-delay relay 103;

During use, hold with a hand piezoelectric vibration piece 102 to prepare to write, press the button 101 beginnings and formally carry out timing test state, now circuit ON, time-delay relay 103 obtains electric work, piezoelectric vibration piece 102 short circuit is not worked, when after the time-delay relay 103 time delay a certain amount of time, its cutoff circuit, thus make time-delay relay 103 dead electricity, now piezoelectric vibration piece 102 electric work, carry out the vibrating alert student time and arrive;

Preferably, described body 1 is provided with a USB interface, is provided with charge management module in described body 1, described battery 104 is connected to USB interface through charge management module, thus is convenient to charge to battery 104;

In addition: it should be noted that above-mentioned detailed description of the invention is only a prioritization scheme of this patent, any change that those skilled in the art does according to above-mentioned design or improvement, all within the protection domain of this patent.
